Low Antibody Response Seen With RA Drug (CME/CE)
(MedPage Today) -- Few rheumatoid arthritis patients treated with abatacept (Orencia) developed immunogenic responses that could interfere with efficacy and safety of the biologic agent, an international study found.
CONCLUSION: The promising effects of patented agents against IL-17A may open new opportunities to therapeutic intervention targeting at different levels of involvement in the pathogenesis of cancer and inflammatory diseases. PMID: 29468982 [PubMed - as supplied by publisher]

CONCLUSIONS: The study findings suggest that the HKM-modifying enzymes are involved in the alteration of HKM, which results in changes in the gene expression of RASFs. PMID: 29465369 [PubMed - as supplied by publisher]
CONCLUSIONS: The proprotein convertase FURIN is significantly upregulated in pSS. Elevated FURIN levels associate with high levels of the Th1 type cytokine IFN-γ and long duration of dry eye symptoms. Patients with high FURIN levels show signs of lower disease activity suggesting that FURIN might have a protective role in pSS. PMID: 29465367 [PubMed - as supplied by publisher]
Authors: Wen H, Liu Y, Li J, Wei D, Liu D, Zhao F Abstract OBJECTIVES: To explore the inhibitory effect and mechanism of 1,25-dihydroxy vitamin D3 (l,25(OH)2D3) on receptor activator of nuclear factor-κB ligand (RANKL) expression in fibroblast-like synoviocytes (FLSs) and osteoclastogenesis induced by interleukin (IL)-22 in patients with rheumatoid arthritis (RA). METHODS: Fibroblast-like synoviocytes from patients with rheumatoid arthritis (RA-FLSs) were cultured and stimulated for RANKL expression with IL-22 in the absence or presence of various concentrations of l,25(OH)2D3, and JAK-2 inhibitor or p38 ...
CONCLUSIONS: Socio-economic deprivation is associated with increased occurrence of all RMDs, and in most cases more deprived patients incur higher health care costs. PMID: 29465359 [PubMed - as supplied by publisher]
CONCLUSIONS: This first report on ARL15 expression in RASF and its likely role in inflammation and metabolic syndromes through a TNF independent pathway, encourages hypothesis-free studies to identify additional pathways underlying RA disease biology.

Authors: Merdler-Rabinowicz R, Hassidim A, Hellou R, Merdler I, Hauser W, Ablin JN Abstract OBJECTIVES: Psychological stress is thought to play a major role in the development and exacerbation of autoimmune diseases in general, as well as in rheumatoid arthritis (RA) in particular. The aims of the current study are to compare retrospective self-reports of childhood maltreatment and lifetime major life/traumatic experiences of American and Israeli RA patients, using standardised instruments, while adjusting for concomitant mental disorders and psychological distress, in order to rule out their part in the subjective...
CONCLUSIONS: In an attempt to detect IgM ACPA, we mostly revealed false positive reactions due to the presence of IgM molecules, which were not specific for citrullinated proteins, and IgG ACPA-IgM RF immune complex. The latter complex had been proposed to play a role in the pathogenesis of RA, and here, for the first time, we have demonstrated its presence in the sera of RA patients.

Authors: Gudmann NS, Hirata S, Karsdal MA, Kubo S, Bay-Jensen AC, Tanaka Y Abstract OBJECTIVES: This prospective study aimed to use serological biomarkers for evaluation of, connective tissue turnover, in a population of 149 Japanese patients with rheumatoid arthritis (RA). It was aimed to investigate how the connective tissue was affected by treatment at follow-up after 1 year (+/- 6 weeks) with either methotrexate (n=23) alone, or in combination with: adalimumab (n=49), tofacitinib (n=27) or tocilizumab (n=50). METHODS: Clinical characteristics were collected and connective tissue turnover, was evaluated by 4...
